Answer:
You need 3/10 buckets of nuts to fill the barrel.
Step-by-step explanation:
We know that 1/5 of a bucket of nuts, fills 2/3 of the barrel.
Then how much we need to fill the other 1/3 of the barrel?
1/3 = (2/3)/2
Then we need half of 1/5 buckets of nuts, this is:
(1/5)/2 = 1/10 buckets of nuts.
Then we need in total:
1/5 + 1/10 buckets of nuts.
we can multiply and divide the left fraction by 2, to get:
(2/2)*(1/5) + 1/10 = 2/10 + 1/10 = 3/10
You need 3/10 buckets of nuts to fill the barrel.
